title: [A case of maxillary tumor--difficulties with diagnosis and treatment].
abstract: Atypical fibroxanthoma is an uncommon mesenchymal neoplasm. It is cytologically malignant but usually clinically being tumor which typically arises in sundamaged skin of the head and neck region. The principal differential diagnoses are spindle cell squamous carcinoma, melanoma and leiomyosarcoma. Immunohistochemistry plays a key role in diagnosis. We report a patient with atypical fibroxanthoma of the maxilla and the neck.
